Bruce's recent experiments with the AVR port of Plan 13 has reminded me that I should make a public release of my Python implementation. I keep thinking that I am going to get to making improvements, but somehow I never seem to get around to do doing it, so rather than just delaying, I'll toss it out in its current state and let people experiment with it. It currently includes a plan 13 module, a module for converting maidenhead grid squares and a couple of example scripts (most notably an "elements" script, for fetching elements, and a "nextpass" script that can be used to find details of the next pass of a satellite, mostly useful for LEO sats, but which illustrate the use of the plan 13 module). Feel free to download and use this code for your own experimentation: it's under an open source license whose only significant feature is to acknowledge Miller's original Plan13 code.
The code runs under Python 2.5, and can be found at:

I'd be interested in hearing of any adaptations, extensions or uses of this code.
